Application filed February 10,1898. Serial No. 669,822. (No minus To allwhom it may concern:

Be it known that I, EUGENE B. CHAPMAN, of Omaha, in the county ofDouglas and State of Nebraska, have invented a new and Improved Devicefor Converting Vibratoryinto Rotary Motion, of which the following is afull, clear, and exact description.

One object of the invention is to provide a' simple and practical devicewhereby a vibratory movement may be converted into a rotary movement andthe direction of rotation be almost instantly changed.

A further object of the invention is to so construct the device that itmay be operated by hand or by power or may be utilized as a toy or a fanor employed to supply power for other purposes.

One invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,- in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective viewof the device used asa toy, illustratingthe manner in which the toy is held and in which the device is operated.Fig. 2 is a section taken substantially on the line 2 2 of Fig..3. Fig.3 is a vertical section through the rotatable sectionof the device and aside elevation of the outer end portion of the vibrator. Fig.4isatrausverse section taken on the line 4 4 of Fig. 1, showing also indotted lines a shifted position of the vibrator. Fig. 5 is asideelevation of the device utilized as a'motive power for'operating a fan,and Fig. 6 is a-transverse section of the vibrator shown in Fig. 5.

The device consists, primarily, of a vibrator A, a rotatable body B, andan instrument G foroperaling the vibrator. The vibrator A consists of abar, stick, or staffof wood, metal, or other suitable material. over,the vibrator is constructed of wood. A stud 10 is formed at the outerendof the vibrator, the said stud constituting a bearing for therotatable body B. Preferably the stud 110. is provided with a taperinginner portion 12, upon which tapering portion the rotatable bodyisadapted to turn. The tapering of the Usually, how-.

stud obviates the necessity of a nut at the outer end of the stud toprevent the rotatable body when in motion slipping oif at the end of thestud. The vibrator is further provided with a series of notches orcorrugations 11 in one of its'longitudinal faces. The number of notchesor corrugations employed and the distance that may intervene betweenthem are immaterial to the operation of the device.

The rotatable body B is virtually a wheel and may be given any desiredshape. In

the drawings a'flat cruciform wheel is illustrated. The wheel may bemade from any desired material and may be a hummingwheel or a propelleror fan wheel, or the wheel may be of disk form, and any form of wheelmay be so decorated as to produce a display of colors or various designswhen the wheelis rotated. An opening 13 ismade at the center of thewheel, which opening may readily receive the stud 10, and said opening13 is of such diameter, as illustrated in Fig. 2, that the wheelwhen onthe stud may have more or less lateral orvertical movement thereon.

The instrument 0 is adapted to be drawn over the notched or corrugatedsurface of the vibrator and is of a hard material, preferably metal. Itis likewise preferably circular in cross-section, as such shape willcause the-least amount of wear on the notched or corrugated surfaceofthe vibrator; but the said instrument may be given any desiredcross-sectional shape without departing from the spirit of theinvention. When the deviceis to be operated by hand, the instrument 0,which is employed to produce the vibrations, is in the form of a bar;-.but where the device is to beoperated by powerthesaid instrument ispreferably given the shape shown in Fig. 5,, in which it is in the formof a link-slide 14.- of much greater width than the width of thevibrator, so that it extends equally beyond each. of its sides, and theupper central portion of the link 14 is reduced in thickness, so that itmay readily enter and leave the notches 11 in the vibrator.

of the said vibrator is secured to a support 15, which may be a frame ofany desired shape or simply a tripod, and a rod 17 is at- IOO ' ioojvi-brator isinclined.

tached to the upper central-pertion of the motor 19 in such manner thatthe rod will be link-slide 14, which rod is carried rearward ,1- througha suitable guide 18, secured to the vibrator, and said rod is connectedwith a given movement. In Fig. 5 the wheel B shown is a fanwheel, andwhen this form of wheel is em-' ployed the stud is preferably madestraight 10 and provided with a nut on its'onter'end, and

j at its innereud by one hand, as shown in v a sleeve or a hub isprojected beyond opposite sides of the fan-wheel, so as to provide anextended bearing for the wheel on the stud, enabling the wheel to traveltrue,

When the device is used as a toy, it is held Fig. 1, with an inclinationin direction of one side, and the instrument 0, by which the vi-'brations are to he produced, is held in the 20 other hand of theoperator, the forefinger being preferably stretched over the upper faceof t'he instrument and carried to a point near where the instrument isto be brought in con-- 'tact with the vibrator. By moving the in- :5strument backward and forward along the notched or corrugated'surface ofthe vibrator A the vibrations thus produced will be communicated to thestud l0, and the stud 10 will so act upon the wheel B,-mo unted there- 0on, as to-cause the said wheel to-revolve, the

number of revolutions of the wheel or its iines in Fig. 4, andcontinuingt-he triction of the instrument 0 on the notched or vcorrugated surface the direction of rotation of thelwheel Bwill .bealmost instantly re I 'versed,- vthe wheel then rotating to-the left, as"shown by the dotted arrow-in Fig. 4, -Such i imtion of the wheel by thevibrations of the,

, vfibmtrol, is in great measure caused'b the studbei'n'g given a quicklateral and aslight 3 nitial movement, first touching at aside of i'lheopening 13 in the wheel, asshown in Fig.

2, at a point which will give an impulse to the whack-next moving towardthe 'posite -'side of the said opening, and then rh (J qnick return 'tothe initial point, again meetking a F -i" Ting and-strikingthe edge ofthe openingini thewheel and imparting to said wheel a fur-s Etherimpulse, the direction of impulse being.

' always opposite to the directionyin which the In Fig.5 the vibrator is"mm-t held with I itsnotchedor corrugated surface perpendic- 'n'lar -orupright. -When the vibrator isheld center thereof, as clearly shown inFig. 6. Instead, however, of holding the'vibrator perpendicnlarorupright and forming its notches or corrugations at one side of thecenter, it

amarraiiged to'one side of tltdlougltudinal can be secured .to itssupport so'as to be held at an inclination in direction of oneside, as

adapted to revolve upon: the said support or to be reciprocated upon thesaid support or "handle tocause thebody to revolveja motor,

Aiion, between said motor 'and reciprocating '--ber adapted .tobereciprocated upon the said ueciprocating means,substantially as deinthisposition, the notches or corrugations described-with reference tothe other figures of the drawings, While the vibrator when 'used as a:toy would notzoperate successfully in the uprightposition when the handinstrn- 7 ment is applied thereto, it successfully operates when thelink form of instrument is employed, by reason of the notches orcorrugations being at one side of the center and the extension of thelink beyond the sides of the vibrator.

I desire it to be understood that parallel bars, sticks, or staffs Amaybe employed, connected Where the wheel is to revolve, in which eventthe notches or corrugations are made upon the opposing faces of the twosticks, stafifs, or bars, and the instrument that is to produce thevibrations is to be reciprocated between and in contact with the saidnotched side surfaces, or that the vibrator may be 9 made of cruciformshape and notches or corrngations may be produced intwo or more of thelongitudinal edges, the exact form of-the vibrator admitting orvariation. l

Having: thus described my invention, -I claim as new and desire tosecure by Letters Patent--- p 1.' The combination-of a support or handlehaving salient points on its surface, a body handle, means comprising arubber adapted and a suitably supported and guided connecmeans,substantially asdescribed.

, 2. Thecombination of a substantially flat support or handle havingsalient points on its edge, a fan adapted to revolve upon the saidsupport or handle, means comprising a rubsupportor handle to cause csaid fan to revolve, a motor and a suitably supported and guidedconnection between said motor and scribed. a

3. The combination of a substantially flat support or handlehaving-'salientpoints on its edge, a body adapted to revolve upon thesaid support or handle, and means comprising a rubber adapted to bereciprocated upon th said flat support or handle to cause the sai bodytorevolve, substantially as described.
